’t Hooft anomalies and the holomorphy of supersymmetric partition functions
Published 2019“…We study the dependence of supersymmetric partition functions on continuous parameters for the flavor symmetry group, GF, for 2d N = (0, 2) and 4d N = 1 supersymmetric quantum field theories. In any diffeomorphism-invariant scheme and in the presence of GF ’t Hooft anomalies, the supersymmetric Ward identities imply that the partition function has a non-holomorphic dependence on the flavor parameters. …”

Crossed products, extended phase spaces and the resolution of entanglement singularities
Published 2024-02-01“…This correspondence provides a blue-print for resolving singularities which are encountered in the computation of entanglement entropy for subregions in quantum field theories. The extended phase space encodes quantities that would be regarded as ‘pure gauge’ from the perspective of the full theory, but are nevertheless necessary for gluing together, in a path integral sense, physics in different subregions. …”

Freedom near lightcone and ANEC saturation
Published 2023-05-01“…Abstract Averaged Null Energy Conditions (ANECs) hold in unitary quantum field theories. In conformal field theories, ANECs in states created by the application of the stress tensor to the vacuum lead to three constraints on the stress-tensor three-point couplings, depending on the choice of polarization. …”
